Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A head-mounted display (HMD) comprising: a shell enclosing a display element and including a dynamic attenuator, the dynamic attenuator comprising a plurality of controllable pixels that control an amount of light from a local area transmitted to an eye box of the HMD; and a controller configured to: determine, based on positional information for one or more objects in the local area surrounding the HMD, whether the HMD is within a threshold distance of an object of the one or more objects in the local area, responsive to the determination, identify a field of view that includes the object, affect polarization of at least a portion of light from the local area by controlling orientations of cells of the controllable pixels in the dynamic attenuator, and adjust a level of attenuation of the light coming over the identified field of view into the HMD by affecting the polarization of at least the portion of light.
A head-mounted display (HMD) features a shell containing a display element and a dynamic attenuator. This attenuator has multiple controllable pixels that regulate the amount of real-world light entering the HMD's eye box. A controller in the HMD uses positional data of nearby objects to determine if the HMD is too close to one. If so, it identifies the specific field of view (FOV) where the object is located. The controller then manipulates the polarization of light coming from that identified FOV by adjusting the orientation of cells within the attenuator's controllable pixels, thereby dynamically controlling and adjusting how much real-world light passes into the HMD over that specific FOV.
2. The HMD of claim 1 , wherein the controller is further configured to: modify content being presented on the display element by adjusting at least one feature of at least a portion of the content presented over at least the identified field of view.
A head-mounted display (HMD) includes a shell with a display and a dynamic attenuator, which uses controllable pixels to regulate real-world light entering the eye box. The HMD's controller analyzes positional data of objects in the surrounding area to detect if the HMD is within a threshold distance of an object. Upon detection, it identifies the specific field of view (FOV) encompassing the object. The controller then adjusts the polarization of light from that FOV by controlling the orientation of the attenuator's pixel cells, thus altering how much real-world light passes through that FOV. Additionally, the controller modifies the virtual content shown on the HMD's display, specifically by adjusting features like brightness or transparency of the content presented over the identified FOV where the real-world object is detected.
3. The HMD of claim 2 , wherein the controller is further configured to: modify the content being presented on the display element by reducing at least one of a brightness and a level of detail in a portion of the content presented on the display element over at least the identified field of view.
A head-mounted display (HMD) features a shell housing a display and a dynamic attenuator. This attenuator employs controllable pixels to manage the amount of real-world light entering the HMD's eye box. A controller determines if the HMD is too close to an object using positional data, then identifies the object's field of view (FOV). It adjusts the light's polarization by orienting the attenuator's pixel cells, thereby controlling real-world light transmission in that FOV. Furthermore, the controller modifies the virtual content displayed on the HMD. Specifically, it reduces features such as the brightness or the level of detail within the portion of the virtual content presented on the display element that overlaps with the identified FOV where the real-world object is detected.
4. The HMD of claim 1 , further comprising one or more sensor elements configured to capture data that are used to generate the positional information.
A head-mounted display (HMD) comprises a shell containing a display element and a dynamic attenuator with controllable pixels that regulate the amount of real-world light transmitted to the HMD's eye box. A controller uses positional information for nearby objects to determine if the HMD is within a threshold distance of an object. If so, it identifies a field of view (FOV) that includes the object. The controller then affects the polarization of light from the local area by controlling the orientation of cells within the dynamic attenuator's pixels, thereby adjusting the level of real-world light allowed into the HMD over that identified FOV. The HMD also includes one or more sensor elements, such as cameras or depth sensors, specifically designed to capture data used by the controller to generate this crucial positional information.

A controller continuously monitors positional information for nearby objects, determining if the HMD approaches an object within a threshold distance. If proximity is detected, the controller identifies a specific field of view (FOV) that includes the object. It then controls the orientation of the attenuator's pixel cells to affect the polarization of incoming light, thereby adjusting the overall level of real-world light attenuation within that FOV. In this particular HMD configuration, the identified field of view that includes the detected object encompasses the entire field of view of the HMD.
6. The HMD of claim 1 , wherein the identified field of view is a field of view that includes the object and a defined angular range around the object.

A controller processes positional data of nearby objects to determine if the HMD is within a threshold distance of an object. Upon detection, it identifies the field of view (FOV) encompassing the object. The controller then affects the polarization of light from that local area by adjusting the orientation of the attenuator's pixel cells, thereby adjusting the light attenuation level within that FOV.

In this HMD, the overall field of view is segmented into different regions surrounding the identified object FOV. Responsive to detecting proximity, the controller instructs the dynamic attenuator to sequentially allow light into the HMD: first, from a region adjacent to the identified object FOV for a specific time interval, and then, from a second region adjacent to the first, over a subsequent time interval.
9. The HMD of claim 1 , wherein the controller is further configured to: measure a rate of change of a distance between the object in the local area and the HMD; and instruct the dynamic attenuator to allow light from the local area over a field of view having a size based on the measurement.
